Perception of tourism development and subjective happiness of residents in Mashhad,Iran

Tourism development affects various aspects of a populace’s life, such as environmental, social, economic, and other areas. This study examines the effect of perceived tourism development on subjective happiness and quality of life among residents of Mashhad City, Iran. A sample size of 384 residents completed a survey. Data analysis was performed using WarpPLS. Results indicated that tourism development had an effect on the residents’ subjective happiness and quality of life (QOL) and the effects of social and micro economic factors on the residents’ subjective happiness and the effects of cultural, environmental, and macroeconomic factors on the resident’s QOL.     

Application of Bayesian Decision Networks for Groundwater Resources Management Under the Conditions of High Uncertainty and Data Scarcity

This paper presents management of groundwater resource using a Bayesian Decision Network (BDN). The Kordkooy region in North East of Iran has been selected as study area. The region has been sub-divided into three zones based on transmissivity (T) and electrical conductivity (EC) values. The BDN parameters: prior probabilities and Conditional Probability Tables - CPTs) have been identified for each of the three zones. Three groups of management scenarios have been developed based on the two decision variables including “Crop pattern” and “Domestic water demand” across the three zones of the study area: 1) status quo management for all three zones represent current conditions; 2) the effect of change in cropping pattern on management endpoints and 3) the effect of future increased domestic water demand on management endpoints. The outcomes arising from implementing each scenario have been predicted by use of the constructed BDN for each of the zones. Results reveal that probability of drawdown in groundwater levels of southern areas is relatively high compared with other zones. Groundwater withdrawal from northern and northwestern areas of the study area should be limited due to the groundwater quality problems associated with shallow groundwater of these two zones. The ability of the Bayesian Decision Network to take into account key uncertainties in natural resources and perform meaningful analysis in cases where there is not a vast amount of information and observed data available – and opportunities for enabling inputs for the analysis based partly on expert elicitation,emphasizes key advantages of this approach for groundwater management and addressing the groundwater related problems in a data-scarce area.     

Idea generation leveraged from value co-creation process enhances new service development performance

This study examines the relationship between value co-creation process, idea generation and new service development performance from the perspective of telecommunication companies. Two dimensions of idea generation tested in this framework are internal and external idea generation, and the probable relationship between these two dimensions is further investigated. The data were collected from 78 marketing managers and were statistically analyzed. The findings show that value co-creation crucially influences both external idea generation and internal idea generation, however, the new service development performance can be enhanced through internal idea generation. Nonetheless, the results show that the external idea generation is vital to influence internal idea generation. This study extends theoretical understanding of how to leverage the value co-creation process for idea generation happenings, while the practical contribution of the research is to realize that new service development performance demands internal idea generation, which is supported with external resources of idea generation.
